Get more efficient operation from your existing Chilled
Water CRAC systems and quick payback through lower
electricity costs and utility rebates.
The Variable Speed Drive (VSD/VFD) Upgrade is easily
installed on your Liebert Deluxe System/3 Chilled Water
systems, providing immediate results with lower electrical
bills.
Typically, CRAC fans run at a constant speed and deliver a constant
volume of air flow. Adding a Variable Speed Drive to the fan motor
allows fan speed and power draw to be reduced as load decreases. A 20
percent reduction in fan speed provides almost 50 percent savings in fan
power consumption.
